WIRE-BENDING MACHINE FOR BALE-TIES.

SPECIFICATIONforming part of Letters Patent No. 271,514, dated January 30, 1883, Application filed dune 8, 1882. tNo model.)

To all whom it may concern:

Be it known that I, C ARLES D. RANDEL, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Wire-Bending Machines for Bale-Ties, of which the following is a specification.

The object of this invention is to bend a loop upon the end of a wire and twist the wire to gether to form one end of a bale-tie or similar article.

In the accompanying drawings, Figure 1. represents a longitudinal vertical section of a machine constructed in accordance with my invention; Fig. 2, atransverse vertical section on the line to w of Fig. 1, looking in the direction of the arrow 1; Fig. 2*, a view of the upper portion of Fig.2, showing the clamp raised; Fig. 3, a transverse section on the line at w of Fig. 1, lookingin thedirection of the arrow 2; Fig. 4, a plan or top view of Fig. 1; Fig. 5, a transverse sectional view on the line y y of Fig. 1; Fig. 6, a side elevation of the machine.

Similar letters indicate correspondingparts.

In these drawings, the letter A designates the frame or bed of my machine, which rests upon legs B, and is constructed similar to the bedof a.turning-lathe. The ends of this bed form the bearings for the actuating-shaft O, to which a revolving motion is imparted by hand or by any other suitable power.

0n the bed'A are secured two head-stocks. D E, the head-stock 1) being cast solid with or otherwise firmly connected to the bed, while the head-stock E is adjustably connected to the bed, so that it can be placed at a greater or smaller distance from the fixed head-stock.

In the fixed headstock is mounted a spindle, F, and on the rear end of this spindleis firmly secured a pinion, a, which gears into a segmental cog-wheel, 1), formed on a portion of the circumference of a disk, I, which is mounted on the actuating-shaft C, so that by turning this shaft an intermittent revolving motion is imparted to the spindle F. On the front end of this spindle is firmly mounted a head, G, which carries the mechanism for bending and for twisting the wire. This head is provided with an abutting shoulder, c, and with an arm, (I, and on the surface of this arm is firmly secured a bracket, 0, provided with a groove for the reception of the wire.

Above this bracket is .a lug, f, formed to correspond to the shape of the'loop to be produced on the wire, and situated at sucha distance from the bracket thatjust room enough is left between the two for the introduction of the wire.

Between the bracket 6 and the abutting shoulder a is situated the bending-arm g. This arm is mounted on a pivot, h, Fig. 4, which is secured in a shoe, h fitted to the outside of the arm d, and which extends through a camshapedslot, 2', in said arm.

From the shoe h extends a pin, j, into aslot, is, formed in a bracket, which rises from a slide, 1, fitted into guide-slots m in the stationary head-stock D.

On the outer end of the slide lis secured a roller-stud, n, and the slide Zis pushed forward, and as the motion of the actuating-shaft progresses the stud it engages with a cam-groove, p, in the cam H, and the slide lis carried back, thus imparting a positive motion to the bending-armineitherdirection. Thisforward-andbackward motion of the slide takes place during the time the spindle F remains stationary, and as the said slide moves forward the pivot h of. the bending-arm 9 moves up in the camshaped slot i, and the bending-arm g is caused to move over the lugf. When the bendingarm is in its normal position its upper surface is level with the surface of the bracket 6, and in said upper surface of the bending-arm is formed a groove corresponding to the groove in the bracket. The wire which rests upon the bracket and upon the bending-arm, and the end of which abuts against the shoulder 0, is bent over the lug] by the motion'of the bending-arm, as shown in Fig. 6, and the bent end of the wire is caught beneathafinger,q. which will be presently described. When the wire has been bent the slide l moves back and the bending arm reassumes its normal position. The bendingarm g and the lug-f, together with suitable mechanism for moving the bending-arm, compose the loop-forming mechanism.

secured to a block, W, fastened to the upper surface of the movable head-stock E bya pivot, s, and the outer end of which extends into a lever, t, Fig. 2, which has its fulcrum on a pin, it, secured in the movable head-stock E, and

The finger qis formed on a lever, 1', which is IOO the lower end of which is held in contact with I a cam, a, by means of a spring, b, Fig. 1. The cam a is mounted on the actuating-shaft O, and when its low portion is opposite to the end of the lever t the finger q is drawn back; but if the high part of said cam acts upon the lever t the finger q is pushed forward so as to project over the groove 0 in the movable headstock, through which the wire is introduced. This groove 0 is formed between the inner edge of the block 0* and a jaw, d, which is fitted into acavity in the movable head-stock, Fig. 1, and the stem 0 of which is depressed by the action of a spring, f, upon the surface of a cam, g, mounted on the actuatingshaft 0. When the bending-arm g has reached the position shown in Fig. 6, the jaw d is raised and the tingerq is pressed t'orward,and by these means the b nt end of the wire is held between the block W and the jaw 01. The bending-arm g is then carried back to its normal position by the action of the camgroove 1) on the roller-stud I, and immediately thereafter the segmental cog-wheel b engages with the pinion a atid a rapid revolving motion is imparted to the spindle F, and since the wire has been bent over the lug f its ends, which are retained between the jaw 11 and block 0*, are twisted together by the revolving motion of the spindle F and its head G. In the face of the abutment 1* is a recess, q, and after the inner end of the wire has been bent. as shown in Fig. 6, both ends or strands lie between the clamp 01 and abutment 1"", as shown in Fig. 2, and when the clamp rises the lip q retains the wires in the position shown in Fig. 2*, so that they are twisted together when the mandrel revolves. As soon as the segmental cog-wheel b releases the pinion a. a lever-pawl, h, drops into a notch, i, Fig. 4, formed in the circumference of a disk,j, which is mounted on the spindle F, the motlon of this spindle is arrested, and the spindle is retained in the position shown in Fig. 1. At the same time the jaw 61 drops and the finger q recedes immediately after the spindle has come to its position of rest, the ejector L is actuated, and the loop of the wire is thrown off from the lug f.

The lever-pawl h has its fulcrum on a pivot, l, secured in a stud projecting from the inner end of the stationary headstock D, and it is guided in a forked stud, m, rising from the outer end of said head-stock.

To the side of the lever-pawl is secured a rod, n, which is depressed by the action of a spring, 0, upon a cam, 11, mounted on the actuating-shaft C, Fig. 3. When the high portion of this cam comes beneath the rod n the lever-pawl h is raised out of gear with the disk 9" and the spindle F is free to be reolved; but as long as the low portion of the cam 19 is beneath the rodgn the lever-pawl h is depressed, and it drops into the notch of the disk j as soon as this notch comes beneath it, thereby retaining the spindle in its position of rest.

The ejector h, Fig. 2, consists of a lever mounted on a pivot, k which is secured in a bracket, k fastened to the bed A. A spring, k draws the ejector back to the position shown in Fig. 2.

From the actuating-shaft projects a pin, k which at the proper moment strikes the lower end of the ejector-lever and serves to actuate the ejector in the desired manner.

What I claim as new, and desire to secure by Letters Patent, is-- 1. The combination, substantially as hereinbeforc described, of the intern'iittently-rotating spindle F, the head carried by the same, the lugf and bracket 0 on the head, the bending arm g, movable on said head. and means for advancing and raising the bending-arm over said lug to bend the wire around the latter, substantially as described.

2. The combination, substantially as hereinbefore set forth, of the spindle F, the head formed on said spindle, the wire-supporting bracket on said head, the loop-forming mechanism, the head-block E, the block W, the movable jaw d, the wire-retaining finger q, and means for operating the loop-forming mechanism and the movable jaw.

3. The combination. substantially as hereinbefore described, of the spindle F, the head formed on said spindle, the wire-supporting bracket on the head, the loop-forming mechanism, the head-block E, the block 1'", the movable jaw d, the wire-retaining finger q, and means for intermittently rotating the spindle and operating the loop-forming mechanism and the movable jaw.
